Massachusetts State Board Esthetics Practice Exam

What type of cells are referred to as fibroblasts?

1. Cells that excrete sweat

2. Cells that stimulate the production of collagen

3. Cells found in the epidermis

4. Cells responsible for pigmentation

The correct answer is: Cells that stimulate the production of collagen

Fibroblasts are specialized cells in the connective tissue that are crucial for the production of collagen and other extracellular matrix components. They play a significant role in wound healing and maintaining the structural integrity of skin and other tissues. The primary function of fibroblasts is to synthesize collagen, which provides strength and elasticity to the skin, helping to support its structure and keeping it firm and resilient. Understanding this role is important for esthetics practice, as the health and function of fibroblasts directly influence the appearance of the skin. The production of collagen by fibroblasts decreases with age, leading to wrinkles and sagging skin, which is why many skin treatments aim to stimulate fibroblast activity or enhance collagen production. In contrast, the other types of cells mentioned serve different functions: sweat-producing cells are related to the body's thermoregulation, epidermal cells primarily serve as barriers and are involved in skin damage repair, and pigment-producing cells are responsible for melanin production, contributing to skin color. Each type of cell has its own distinct roles in maintaining skin health, but fibroblasts are specifically known for their critical function in collagen production.
